The fuel smell isn't coming from there. Your EHA is probably leaking.

And an "EHA" is? Sorry for my ignorance. The smell does seem to be coming from the end of that hose. I can smell it nowhere else. Strange.

EHA stands for electro Hydraulic Actuator. It is mounted on the fuel distributor and is what trims the fuel supply to the injectors. Unless you have a leaking hose or loose fitting, there isn't anything under the hood to leak except the EHA which is prone to leaking.

Your best option is to get both front and rear mufflers (youll likley be able to get a discount and get both for less than $300.00 shipped) When one goes the other is often not far behind.
They are excelent mufflers... and will outlast any cheaper alternative saving money in the long run... and maintan the value of the car.

The box you are referring to is most likely the charcoal canister. It absorbs fuel vapors, and is basically a smog control device. It also helps keep things from getting too stinky.

Thanks. I am 99.9% sure that is where the smell is coming from. It is not strong, but when I put my nose close to it, I can smell it, but only then.

I do not even know where that "fuel distributor" is, but as mentioned, there was no fuel smells anywhere else. I would not have even smell it at the hose at this box if not for me looking closely at the power steering pump.

So, there is not real immediate concern that this hose is cracked since it is not a fuel line?


Also- speaking of power steering, when it is "full" is that all the way to the "brim"? I did not notice a "full" line anywhere inside the reservoir. Also- seems that MB PS fluid is the way to go?

Thanks again,

To update, I checked my gauge today and when it hits 1500 RPMS, it is already at the "3" bar, which is where Hattaras said it should be. When idling however when in drive (idling at 500 RPM)and fully warm, it drops to slightly above the "0" which concerns me- should I be concerned since it is at "3" @ 1500 rpms? I also checked it and when it is idling at full temperature when in park (around 750 RPMS), it is right at the "1".

I know the oil is old and needs changing. I hope that brings it up further than it is when it is fully warm and idling in drive.

Thanks in advance.

Hi 86

Really, change your oil and filter - then see if you have an issue to deal with regarding oil pressure, but as said before - it all sounds fine.

Re PS fluid - yes, up to the top.

Cheers and have a great xmas and N/Y.

beware of fundamentalists!

Change your oil already! Pull the oil cap off and see if you have oil up their.

Yeah, as you have already read on the other topic, I changed the oil this evening. I removed the oil cap with the engine running and there is a stream of oil coming out of that tube onto the cam lobes. I guess all is well.

Well, I thought all was fine, because when I changed the oil, the gauge was reading higher. As mentioned before, when @ 1500 rpms, it is already at the "3", which I was told was normal. When idling in park, with engine warm, it is between the "1" and "2". When it is at 80*C, at idle and in park, it was between the "0" and "1". Today, I had to run several errands in town and the temperature was just above the 80*C mark, (where the needle was horizontal). I stopped at a traffic light and looked and the oil pressure gauge was nearly at "0"! Does this mean my engine is completely worn out? It still runs quietly, aside from some slight lifter chatter from the passenger side valve cover, which seems to be common on these cars. Also, it does not smoke. Should I use a different grade of oil? I used Rotella 15W-40, as recommended.

Thanks

I'd hook a mechanical guage up to confirm those numbers before doing anything more.

You can run engines quite a while with low oil pressure but eventually they will blow up.

I remember one of my dads friends had a boat with an ancient pair of Cummins na V8 diesels in their. One had no oil pressure at idle and only a bit at speed. But it ran for almost two seasons before it spun a bearing. The owner wanted to repower the boat with modern diesels and decided to wait for it to blow.

Thanks. I was reading a post (see 140 oil pressure thread) about another persons oil pressure question and posted more information there. When the engine is at 80*C, the pressure is fine, but over 80*C, it seems to drop way too low when it is idling in gear, such as a stop light or something. It is still going to about the "3" mark when I hit 1500-1700 rpms though, which is better than the 3000 rpm I have been hearing about.

I have had the engine running with the oil cap off and oil is coming out of that bar and onto that cam. So, I guess the pressure is OK. I just have uncertainties.

Maybe I should go with a different grade of oil if the gauge checks out OK, or else not worry about it and drive it until the wheels fall off.
